Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02486 | $0.02486 |
| Opus 5 | $0.01243 | $0.01243 |
| Sonnet 5 | $0.00497 | $0.00497 |
| Haiku 4.5 | $0.00249 | $0.00249 |
Grade A, and why
sjungling-claude-plugins CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Repository Purpose
This is a personal collection of Claude Code plugins. Plugins extend Claude Code's functionality through custom tools, hooks, and integrations via the Claude Code plugin system.
Development Commands
This repository doesn't require a build step - it's a collection of markdown-based plugin definitions. Key operations:
- Validate marketplace structure: Ensure
.claude-plugin/marketplace.jsonis valid JSON - Test plugin locally: Use
/plugin marketplace add /Users/scott.jungling/Work/sjungling-claude-pluginsto add this marketplace - Install plugin: Use
/plugin install <plugin-name>@sjungling-pluginsto test installation - Validate agent/command syntax: Check YAML frontmatter in markdown files is properly formatted
- Bump plugin version: Always increment
versioninplugins/<plugin-name>/.claude-plugin/plugin.jsonwhen making any changes to a plugin. Claude Code won't detect updates on reinstall without a version bump.
Architecture
Plugin Marketplace Structure
The repository uses a marketplace configuration (.claude-plugin/marketplace.json) that:
- Defines the plugin root location (
plugins/directory at repository root) - Lists all available plugins with metadata (version, description, keywords, category)
- Maps plugin components (agents, commands) to their file locations
- Enables plugin installation via
/plugin install <name>@sjungling-plugins
Plugin Component Types
Each plugin can contain:
- Agents (
agents/subdirectory): Custom agent definitions with specialized prompts and behaviors - Commands (
commands/subdirectory): Slash command implementations that execute workflows - Skills (
skills/subdirectory): Reusable prompt templates that Claude automatically invokes based on context - Components are defined in markdown files with YAML frontmatter (skills and agents require frontmatter, commands don't)
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
